Understand the expression: Understand the expression ln4e. The expression ln4e means the natural logarithm of the fourth root of e, where e is the base of the natural logarithm, approximately equal to 2.71828. The fourth root of a number is the number that, when raised to the power of 4, gives the original number. So, we need to find the fourth root of e and then take the natural logarithm of that value.
Calculate the fourth root of e: Calculate the fourth root of e. The fourth root of e can be written as e(1/4). This is because the nth root of a number can be expressed as that number raised to the power of 1/n.
Take the natural logarithm: Take the natural logarithm of the fourth root of e. Since the natural logarithm ln(x) is the inverse function of the exponential function ex, we have the property that ln(ex)=x. Applying this property to our expression, we get ln(e1/4)=41.
